Description
Deskin through 3.3.4.3 contains a privilege escalation vulnerability in the com.deskin.service.installer XPC service that allows local unprivileged attackers to execute arbitrary installer packages as root by connecting to the root-owned service without authentication. Attackers can invoke the privileged installer method to run an attacker-supplied installer, achieving full root compromise of the macOS host.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-11318 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.
